I installed again, this time I used partition 1 and named it "HP Mac" GUID.

Customization settings were:

SMBIOS --> AppleSMBIOS-27MBmem and
Graphics --> NVinject-256


Results: The computer is recognizing the mouse in every boot, but I'm still getting the "root device error" without typing in the rd=disk0s2. I finally got the computer to get the root disk, and it continues but suddenly stops at.
